Properformance RapidDrive BCAA 5000 features our most advanced RapidDrive Amino Acid Technology. These Branched Chain Amino Acids (BCAA) have been pulverized, or "micronized," from large molecules into smaller particles that are easier to absorb and deliver fast fuel for powerful performance. Now you can fully power your muscles to new levels for optimum performance.

Using Pro Performance RapidDrive BCAA 5000 can help maintain and rapidly replenish BCAA stores. Each serving supplies 5000mg of pure BCAA and mixes easily in any beverage or sports drink.

GNC's Product Development Scientists were challenged to create an advanced delivery form of amino acid supplements, a critical sports nutrition component that can be used in the regimen of top athletes. The result of these research efforts led to the creation of the RapidDrive Amino Series, a core group of superior and fast-absorbing amino acids for rapid muscle fueling results. This unique technology is much more advanced compared to regular amino acids. Because our team is dedicated to continually improving sports nutrition products, the Pro Performance RapidDrive Amino Series helps you, the athletes, get fast fuel for your muscles.

For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

This supplement has been used in connection with the following health conditions:

Athletic Performance and Mental Decline During Exercise at Extreme Temperature

Dose: Refer to label instructionsSome research has shown that branched-chain amino acids help prevent muscle loss at high altitudes, prolong endurance performance in the heat, and improve exercise-induced declines in mental functioning.

Dose: Refer to label instructionsSome research has shown that branched-chain amino acids may support immune fuction and improve infection at high altitudes and prolong endurance performance in the heat.

Athletic Performance and Mental Decline During Exercise at Extreme Temperature

Dose: Refer to label instructions

Some research has shown that supplemental branched-chain amino acids (BCAA) (typically 10 to 20 grams per day) do not result in meaningful changes in body composition,1 nor do they improve exercise performance or enhance the effects of physical training.2, 3, 4, 5, 6, 7 However, BCAA supplementation may be useful in special situations, such as preventing muscle loss at high altitudes and prolonging endurance performance in the heat.8, 9 One controlled study gave triathletes 6 grams per day of BCAA for one month before a competition, then 3 grams per day from the day of competition until a week following. Compared with a placebo, BCAA restored depleted glutamine stores and immune factors that occur in elite athletes, and led to a reported one-third fewer symptoms of infection during the period of supplementation.10 Studies by one group of researchers suggest that BCAA supplementation may also improve exercise-induced declines in some aspects of mental functioning.11, 12, 13

The branched-chain amino acids (BCAAs) are leucine, isoleucine, and valine.
BCAAs are considered essential amino acids because human beings cannot survive
unless these amino acids are present in the diet.

Bought it because they were out of Optimum Nutrition's BCAA unflavored. I opened the container and it certainly doesn't look like 50 servings., the container was just under 1/2 full. At least with ON's you get 60 and it's darn near full.

I mix it with the fruit punch and it's not bad. By itself, it tastes awful like all of the other "unflavored" supps. I take this intra-training as my pre and post shakes have good amount of bcaa's in it already.

I really like this BCAA product. I take a scoop with a protein shake after morning workouts. My body feels fresh and recovered and ready for a workout the next morning. The taste is okay but keep in mind leucine is made from fermented corn which probably gives it the sour/bitter taste. I will probably purchase the product again.

I bought this "un-flavored" thinking I would mix it with a shake and was shocked the first time I had it. The taste is very strong/ bitter and made me gag even when mixed with a shake or fruit in the blender. Also the powder is very fine/ talc like and it puffs all over each time you open & close the container. I will suffer through the rest of the container since it cant be returned but will buy in tablet form or another brand next time. It does work well for recovery but the down sides out-weigh the pros.

When I bought this product I expected a neutral flavored powder, you know something that tasted like nothing. That was my idea of non-flavored. The taste was a shocker. I tried to pre workout mixed with milk and a berry flavored enzyme/energy mix. That didn't even come close to covering up the taste. Most of the time I mixed the product with Muscle Milk Vanilla or Strawberry in my post work out shakes. Muscle Milk tastes really good and Rapid Drive even made it taste bearably bad. I ordered the fruit punch so I can drink Rapid Drive by itself pre-workout. Leucine is a precursor of HMB which has been shown to increase muscle mass in pigs. I just drink it most of the time with the pretense that it's good for me or will help achieve my goals.

Like other users have said do yourself a favor and try the fruit punch version. I felt queezy every time I tried to take it. It is comparable to ground up chalk and is very overpowering no matter what I've mixed it with so far. Other than that, great product.
